Abstract
resumo patente de invenção: "segmentação em aplicações de imageamento de diagnóstico com base em análise estatística ao longo do tempo". a presente invenção refere-se a uma solução de segmentação para uso em aplicações de imageamento de diagnóstico. um método de segmentação de processamento de dados correspondente (a1 a a10) compreende: fornecer (a1 a a4) uma representação ao longo de um período de tempo de análise diferente de zero de uma parte do corpo que está sendo perfundida com um agente de contraste, a representação que compreende, para cada localização de um conjunto de localizações da parte do corpo, uma indicação de uma resposta ao longo do período de tempo de análise da localização para um sinal de interrogação; calcular (a5 a a6), para cada localização selecionada de um conjunto de localizações selecionadas, o valor de pelo menos um parâmetro estatístico de uma distribuição estatística da resposta ao longo do período de tempo de análise da localização selecionada, em que o conjunto de localizações selecionadas compreende todas as localizações ou uma parte das mesmas; e segmentar (a7 a a9) as localizações selecionadas de acordo com uma comparação entre os valores do dito pelo menos um parâmetro estatístico para as localizações selecionadas com pelo menos um limite de segmentação.patent abstract: "segmentation in diagnostic imaging applications based on statistical analysis over time". The present invention relates to a segmentation solution for use in diagnostic imaging applications. A corresponding data processing segmentation method (a1 to a10) comprises: providing (a1 to a4) a representation over a non-zero analysis time period of a body part being perfused with a contrast agent a representation comprising, for each location of a body part location set, an indication of a response over the location analysis time period for an interrogation signal; calculate (a5 to a6), for each selected location of a set of selected locations, the value of at least one statistical parameter of a statistical distribution of the response over the analysis time period of the selected location, where the set of locations selected comprises all locations or a portion thereof; and segmenting (a7 to a9) selected locations according to a comparison of said at least one statistical parameter values for selected locations with at least one targeting threshold.
